Embodiment Construction

[0021] Below in conjunction with accompanying drawing, technical scheme of the present invention will be further described:

[0022] see Figure 1-2 A system for increasing soil moisture in arid and semi-arid areas proposed by the present invention includes rock wool boards, cooling air water collection systems and water delivery tanks; the rock wool boards are laid on the soil, and the rock wool boards adopt agricultural rock wool boards; wherein, The refrigerated air water collection system includes a refrigeration device, an electrical storage system and a control system. The electrical storage system includes a solar or / and wind power generation component and a battery. The solar or / and wind power generation component is connected to the battery through a circuit to store energy in the battery. Then the storage battery supplies power to the refrigeration unit. Wherein, the control system includes a rain and snow sensor and a controller, and the signal output terminal of t...

Abstract

The invention provides a system for increasing soil moisture in an arid and semi-arid region. In a water-deficient region, a thermal insulation material and condensed water produced by a temperature difference generated in a refrigeration process are used for gradually increasing the moisture of soil. A cooling air water-collecting system is adopted, power is supplied to a refrigeration device by renewable energy sources such as solar energy or wind power, moisture is obtained from wet air through a refrigeration dewing method, and the condensed water is introduced into the soil through a water delivery pipe; moreover, a rock wool board is paved on the surface of the soil, so that evaporation of moisture on the surface of the soil is reduced or prevented, water is injected into the soil by continuously absorbing air moisture, the water accumulating function of the soil is added, and the moisture of the soil is further increased.

Description

technical field [0001] The invention relates to the technical field of improving soil moisture in arid and semi-arid areas; in particular, it relates to a system for increasing soil moisture in arid and semi-arid areas. Background technique [0002] Land with dry soil and poor fertility occupies a large area. In China, at least 300-400 million mu of land lacks water sources, the soil layer is less than 50 cm thick, and the organic matter content is very low. Worldwide, most of the inland areas in central Africa, western and northern South America, West Asia, Central Asia, and the coastal areas of Australia have sparse vegetation and few rivers. As the temperature rises, the frequency of extreme climates such as snow line shifting, glaciers melting, strong winds, and extreme heat increases significantly, and desertification and drought expand in many areas. Soil erosion is serious in many areas, food production is reduced, and disasters are frequent. Sandstorms and smog have...
